Explanation:

• Question 21: Tinea is the technical term for ring - worm, caused by dermatophyte fungi, not parasites or mites, and not highly contagious in the sense described for some other conditions.
• Question 22: Scabies is caused by the mite Sarcoptes scabiei and its main symptom is intense itching and a rash that may have blisters and bumps. Yellow crusts on the scalp are not typical scabies symptoms, nor are scales with a distinct odor or greasy/waxy scales.
• Question 23: Head lice are mainly transmitted through head - to - head contact with an infected person. They do not cause tinea barbae or scabies, and they can only live about 1 - 2 days without a host.
• Question 24: A furuncle is the technical term for a boil, which is an infection of the tissue around a hair follicle. A carbuncle is a cluster of furuncles, canities is related to graying of hair, and hirsuties is excessive hair growth.
• Question 25: Folliculitis barbae (pseudofolliculitis barbae) is an inflammation of the hair follicles caused by ingrown hair, not by head lice, staphylococci in the context of being a type of carbuncle, or by malassezia causing scalp inflammation.
